The CASTELLI ARIA SHELL JACKET is clearly the technical cycling jacket you need for optimal wind protection.
Its incredible compactness will surprise you. It fits easily into one of your back pockets when folded in on itself, allowing you to get it out and on quickly.
The microfiber fabric on the front and sleeves cuts through the wind and protects you from cold snaps, while the ultra-ventilated Mesh side panels and sleeve inserts help wick away sweat. You'll feel as dry as a cocoon.
The stretchy back allows for a comfortable, close-fitting fit, so the fabric floats in the wind.
